METHOD FOR ACTIVATING WATER, METHOD FOR CLARIFYING WATER IN CLOSED LAKE AND MARSH AND APPARATUS THEREFOR

摘要

PURPOSE:To activate and effectively clarify water of closed lakes and marshes by ejecting the water to be treated through a pipe wherein a magnetic field is formed by a magnet. CONSTITUTION:Pumped water of lakes and marshes fed by pressure into a delivery pipe 12 is ejected at a high speed from a nozzle 16 of the end, at which the diameter is reduced, of the pipe 12 into a jet pipe 18 which is connected coaxially in front of the delivery pipe 12 to cover the nozzle 16. Since an outside air intake pipe 20 is connected to the rear end of the jet pipe 18, outside air to be mixed with the water is sucked during the ejection of the water from the nozzle 16. A plurality of ring-shaped permanent magnets 24 are engaged on an end larger-diameter part 22 of the jet pipe 18 so that the water is affected by the magnetic field of the magnet 24. Contamination sources of clay, iron, manganese, etc., are destroyed by the static breakdown of colloidal particles so that clarified water is discharged.
